Specification of Letters Patent.

Application filed February 18, 1914. Serial No.-819,532.

specification, reference being had therein to the accompanying drawing.

This invention relates to hfe boats and has for its object to provide a boat of such class, in a manner as heremafter set forth,

with means to prevent the capsizing of a boat, and further with means to maintain the boat in an upright position when traveling through a heavy surf.

Further objects of the invention are to provide a life boat which is comparatively simple in its construction and arrangement, strong, durable, eiiicient and convenient 1n its use, readily set up, and inexpensive.

With the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of parts as hereinafter more fully descrlbed and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In describing the invention in detail reference is had to the accompanying drawings wherein like reference characters denote corresponding parts throughout the several views, and in which Figure 1 is a transverse sectional viewof a life boat in accordance with this invention; Fig. 2 is a side elevation, broken away; Fig. 3 is a sectional detail of a rocking arm.

Referring to the drawings in detail 3 denotes the hull of a vessel which is provided with a solid keel 4, with this exception, that the keel centrally thereof is formed with a transverse opening'5. Each side of the hull 3 is formed with a vertically disposed pocket 6 which at its lower end communicates with an opening 5 and at its upper end communicates w1th an opening 7. Arranged within each of the pockets 6, in proximity to the opening 7 is a horizontally disposed eye 8 for the purpose to be presently referred to. The inner wall of each of the oc'kets 6, at its lower end, diverges, as in icated at 9, whereby the lower end of each of the pockets 6 is of greater width than the upper portion of the pocket. -Attached to the hull 3, centrallythereof, and depending into the opening 5, is a hanger lO', carrying an annular member orlink 1 1, to which is loosely connected a suspension arm" 12, the latter beingprovided intermediate its ends with an opening13. Attached to the lower end of the arm 12 is an annular link 14:, to which is loosely connected a weight 15. Arranged in each of the pockets 6, and extending through 1 an eye,;=8, is a vertically disposed rod 16, having a head 17, thelatter engagmg the eye 8 to arrest downward movement of the rod 16. The lower end of each of therods 16 curves inwardly as at 18, and the said end 18 extends between the bifurcated upper end 20 of a rocking arm 21. The end 18-of the rod 16 is pivotally connected to the bifurcated end 20, of the rocking arm Patented July' 28, 1 14.

21, by a pin 22. Each of the rocking arms 21 are curvilinear in contour and ride against the faces of the arm 12.. Each of the,

rocking arms is provided with an opening 21 and extending through said openings is a curved bar 23 which connects the lower portions of the rocking arms together. The bar 23 extends loosely through the openings 21 and is formed with downwardly bent ends 24 which ride against rollers 25 ar ranged within the opening 21 of'the rocking arms 21.

in the keel and extend across the opening 5. When the hull of a vessel swings, due to swell of the waves or heavy surf, it will assume the position shown in dotted lines in Fig. 1, or such action will be had against the action of the weight 15 and arm 12, and as the arm 12 will always remain in a ver-. tical position, it is obvious that the rock ing arms will be shifted, tending to resist the overthrowing or capsizing of the boat, and under such conditions reduce capsizing to a minimum. The action of the rocking arms will be the reverse of that shown in dotted lines in Fig. 1, when the boat is turned in a direction opposite to that illustratedin dotted lines. The rollers 25 prevent any binding action between the rod 23 and the rocking arms, when the rocking arms are shifted from normal position. The weight 15 and arm 12,- in connection with The rocking arms 21 are further- 'i more pivotally mounted upon bars 26 seated the rocking arms, permanently tend. right the boat on its keel:

What I claim is:

l. A life boat comprising a hull provided with a keel having a transverse opening, a weight and arm loosely connected to the hull and depending below the keel, a pair of vertically movable bars carried by the hull and having curved lower ends arranged in said opening, and rocking arms pivotally connected to the said ends and with the hull, and moving against opposite sides of said arm.

2. A- life boat comprising a hull provided with a keel having a transverse opening, a weight and arm loosely connected to the hull and depending below the keel,a pair of vertically movablebars carried by the hull and having curved lower ends arranged in said opening, rocking arms pivotally connected to the said ends and with the hull, and moving against opposite sides'of said arm, and

and depending below the keel, a pair of vertically movable bars carried by the hull and having curved lower ends arranged in said opening, rocklng arms pivotally connected to the said ends and with the hull and moving against opposite sides of said arm, means for loosely connecting said rocking arms together, and means for limiting downward movement of said rods.

In testimony whereof I afliX my signature in the presence of two witnesses.
